SPRING BED-BOTTOM.

SPECIFICATION forming part of Letters Patent N 0. 732,392, dated June30', 1903.

Application filed January 2'7. 1902. Serial No. 91,502. (No model.)

To ctZZ whom, it may concern:

Be it known that I, CHARLES D. BROU- YETTE, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in SpringBed-Bottoms, of which the following is a specification.

My invention relates to improvements in the manner of securing spiralsprings in the lower surface or base of a conical spiral springbed-bottom; and its objects are, first, to lessen the cost ofconstruction; second, to greatly strengthen the base against beingthrown out of square, and, third, to so unite the parts as to positivelyprevent separation or dislocation unless it be desired to repair thespring and yet be so that the spring may be readily and easily removedwithout injury to or distortion of parts. I attain these objects by themechanism illustrated in the accompanying drawings, in which Figure 1 isa bottom plan of a portion of a spring andbase, showing the manner ofsecuring the springs to the tie-rods of the base. Fig. 2 is an elevationof the same; and Fig. 3 is a plan of the tie-rods, showing the manner ofintroducing and applying the spring and passing it to position to secureit to the tie-rods.

Similar letters refer to similar parts throughout the several views.

In the construction of this base the longitudinal tie-rods A have adepression a a a formed for the reception of each spring and the lateraltie-rods B have an offset 19 b b, which coacts with the longitudinaltie-rod A and the end of the spring 0 to form the support for thesprings, and they are woven together as follows, which is the only waythe spring can be connected with the base.

In Fig. 3 the lateral and longitudinal tierods are shown as in positionwith the bedbottom bottom side up and the tie-rods held firmly in placeto receive the lower ends of the springs, and to enter the spring itmust be held with the base of the cone upward as shown, and the endoCmustbe passed through under the oifset in the lateral tie-rod betweenit and the longitudinal tie-rod at the depression at in position so thatend C may be drawn back over the arm of the offset in the lateraltie-rod, as shown, when the base of the spring must be carried over inthe direction of the arrow toward D and passed between the tie rods andto place below them, as indicated by the dotted lines in Fig. 3 and asshown in Figs. 1 and 2, so that the portion 0 of the spring will rest inthe depression a, and the spring having been carried over the end Crests upon the top of the lateral tie-rod and against the side of thelongitudinal tie-rod, formin g a brace or braces that will avert thedanger of throwing the bed-bottom out of square. The portionc passesthence over the longitudinal tie-rod, under the opposite arm of the 6offset in the lateral tie-rod, and thence over the rod and under thelongitudinal tie-rod at C, where it presses upon the rods withsufficient force to cause a firm bearing of the portion-c upon theportion a of the depression in the longitudinal tie-rod, and theportion 1) of the offsetin the lateral tierod rests against thelongitudinal tie-rod at a. It is evident that this connection cannot bemade in bedbottoms where it is desired to use the hour glass spiralspring, but with the single cone made to alternate right and left theconstruction is so firm, by reason of the brace secured by the ends 0,as hereinbefore suggested, that it is practically impossible to throwthe bed out of form diagonally, thus securing a practically squarebed-bottom under all conditions. I

-If it is desired to remove a spiral spring from this construction, thespring must be swung back between the tie-rods in a direction oppositethat indicated by the arrow in Fig. 3 and up to the position of thesolid lines in said figure and spring the end C i from over the lateraltie-rod at b, when the end 0 C may be drawn from its bearings betweenthe tie-rods and the spring readily removed. By this means a bed-bottommay be readily repaired without bending or distorting the tie-rods whenremoving the spring, 9 5 and, further, the hooked end C may be formedupon the end of the spring while in the process of being coiled'and the.spring complete inserted much more quickly and conveniently than withany other construction now practiced.

It is not absolutely necessary that the end C of the spring be made topress solidly against the side of the longitudinal tie-rod; but Iconsider it far preferable in consequence of the greater strengththereby gained and the perfect form of bed attained and retained.

The vital feature of this invention, which is my discovery, is thereversing of the position of the spiral spring with reference to thebase wires in order to assemble parts or remove them from each other.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

1. The combination in a spring bed-bottom of longitudinal tie rodshaving depressions, lateral tie-rods having V-shaped offsets extendingbeyond the depressions and bearing upon the surface of the longitudinaltie-rod, a conical spring having one end near the side of thelongitudinal tie-rod thence passing to one point of angle of the offset,forming a hook and passing around the lateral tie-rod at the point ofangle, thence across the longitudinal tie-rod in the depression, thenceto and around the lateral tie-rod at the other point of angle of theoffset, thence a coil of the spring passing across the longitudinaltierod in position to exert the torsional force of the spring upon theoffset of the lateral tierod interweaving it with the longitudinaltierod, substantially as and for the purpose set forth.

2. The combination in a spring bed-bottom of longitudinal tie-rodshaving depressions, lateral tie-rods having'V- shaped offsets the pointof said offsets bearing upon the surface of the longitudinal tie-rodsnear the points of angle of said depressions, spiral springs having theends near the sides of the longitudinal tie-rods, thence under andaround the lateral tie-rods at the point of angle of the offset forminga return hook and passing under the longitudinal tie-rod at the point ofdepression, thence over and around the lateral tie-rod at the otherpoint of angle of the offset, thence over the longitudinal tie-rod,substantially as and for the purpose set forth.

The combination in a spring bed-bottom of a coil-spring, a transversewire having a long V-bend, and a longitudinal wire, interwoven by thewires having the following positions relatively: the wire of thecoil-spring passing, commencing at one end thereof, under the transversewire and over the adjacent leg of said long V-bend, under thelongitudinal wire, over the other leg of the long V-bend and under thetransverse wire adj acent thereto, and over the longitudinal wire,thence continuing in a coil which is substantially at right angles tothe plane of the web-wires which intersect at the apex of the longV-bend, the transverse wire passing over the longitudinal wire,substantially as and for the purpose set forth.

4. In a spiral-spring bed-bottom, a longitudinal tie rod havingdepressions, lateral tie-rods havin gV-shaped offsets, spiral springsinterwoven therewith by resting on the longitudinal tie-rod, thencepassing under the lateral tie-rod and around over the arm of the oifsetat the point of angle, thence under the longitudinal tie-rod at thedepression, to and over the other arm of the offset and around under thetie-rod at the opposite point of angle, thence the end extending to, andat right angles with the side of the'longitudinal tie-rod, substantiallyas and for the purpose set forth.
